The maternal relationship between Elizabeth May Ratliff and her daughter Ida Pearl Bown is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant TS.

The segmental (via DNA segment triangulation) and total DNA shared between TS and other confirmed descendants of Thomas Boswell Ratliff/Sarah A. Henderson is consistent with the expected ranges for their respective relationships. Since TS descends from Thomas Boswell Ratliff/Sarah A. Henderson through Elizabeth May Ratliff and her daughter Ida Pearl Bown, the presence of significant shared DNA between TS and other known descendants of Thomas Boswell Ratliff/Sarah A. Henderson validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple Thomas Boswell Ratliff/Sarah A. Henderson through Elizabeth May Ratliff to Ida Pearl Bown, and ultimately to TS, confirming this direct ancestral connection through multiple generations.
